Solar Panel Efficiency explained. Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%.
As explained below, solar panel efficiency is determined by two main factors: the photovoltaic (PV) cell efficiency, which depends on the solar cell design and the type of silicon used, and the total panel efficiency, which depends on the cell layout, configuration, and panel size.
Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
The latest version 65 of Solar cell efficiency tables, released in November 2024, is now available but requires a login or payment. Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5.
